IMPROVED DEVICE FOR BENDING IRON BARS FOR TRUCKS.

Specilieation forming part of Letters Patent No. 42,978. dated May 3l,1864.

To all whom it may concern:

- Be it known that I, BOBERT B. WEAVER, of Steubenville, in the countyof J eerson and State of Ohio, have invented a new and Improved Devicefor Bending Iron Bars for Oar- Trucks; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willena-ble others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, making a part of' thisspecitcation, in which- Figure l is a front view of Iny invention; Fig.2, a transverse vertical section of the same, taken in line :v x, Fig.1.

Similar letters of reference indicate like parts.

This invention relates to a new and useful machine for bending iron barsin proper shape for car-trucks; and it consists in the employment or useof a bed in the form in which it is designed to bend the bars, inconnection with a jointed clamp, levers, and a screw or its equivalent,all arranged as hereinafter set forth.

A represents a bedpiece, which is constructed of metal, and having itsface or upper side made in the form in which it is designed to bend thebars. (See Fig. 1, in which a represents a central horizontal part; b b,two inclined parts, and c c two horizontal parts at the ends of thebed.)

B is the clamp, also constructed of metal, and formed of Athree parts, dc e, connected together by hinges or joints f. The central part, d, hasa horizontal position and is directly over the part a of the bed, and isoperated or raised and lowered by means of a screw, C, the nut of whichis in a horizontal bar, D, supported by uprights g g, which, inconnection with a bar, h, at the back of d, may also serve as guides forthe clamp. The

parts e e ot' the clamp B are directly over the parts b b e c of thebed, and to the outer ex d of each part b there is secured by a link or-stirrup, E, a lever, F. To each end ofthe bedpiece there is secured avertical rack, G. The bed-piece A has a longitudinal groove, i', made init to receive the bar to be bent, and the central part, a, of the bed isprovided with two steady-pins, jj.

The operation isas follows: The clamp B is raised to a height necessaryto admit of the bar, properly heated, being laid centrally on thebed-piece, the steadypins j j passing through holes in the bar. Theclamp B is then forced down by means of the screw O until the centralpart, d, is firmly pressed down upon the bar over the part a of thebedpier-e, and the parts e e are then brought down until the leversFcatch into the racks G, when said levers are employed for bringing theouter parts ot' the bar down upon the parts b b c c ot' bed. The parts ecof the clamp are raised by means of ropes H H, pressing over pulleys klc on the bar D, said ropes having weights attached to their ends.

By means of this device the bars may be bent with great facility and ofa uniform shape.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is The bed-piece A, in combination with theclamp B, formed of three parts, connected to,- gether by hinges orjoints, the levers F F, racks G, and the screw C, or its equivalent, allarranged to operate substantially as and for the purpose herein setforth.
